**Tasks:**
1. Implement TypeScript types (`framework/src/types/index.ts`)
2. Implement SessionReader (`framework/src/collector/session-reader.ts`)
3. Implement MessageParser (`framework/src/collector/message-parser.ts`)
4. Implement TimelineBuilder (`framework/src/collector/timeline-builder.ts`)
5. Write tests

**See:** [tasks/eval-framework/01-session-reader.md](../tasks/eval-framework/01-session-reader.md)

**Estimated Time:** 4-6 hours

---

### Phase 2: Core Evaluators

**Goal:** Implement evaluation logic

**Tasks:**
1. Implement BaseEvaluator
2. Implement ApprovalGateEvaluator
3. Implement ContextLoadingEvaluator
4. Implement DelegationEvaluator
5. Implement ToolUsageEvaluator
6. Write tests

**See:** [tasks/eval-framework/02-evaluators.md](../tasks/eval-framework/02-evaluators.md)

**Estimated Time:** 8-10 hours

---

### Phase 3: Test Runner

**Goal:** Execute test cases and generate results

**Tasks:**
1. Implement test case loader
2. Implement SessionAnalyzer
3. Implement TestRunner
4. Create test case library
5. Write tests

**See:** [tasks/eval-framework/03-test-runner.md](../tasks/eval-framework/03-test-runner.md)

**Estimated Time:** 6-8 hours

---

### Phase 4: Reporters (Future)

**Goal:** Generate useful reports

**Tasks:**
1. Implement ConsoleReporter
2. Implement JSONReporter
3. Implement MarkdownReporter
4. Add trend analysis

**Estimated Time:** 4-6 hours

---

## Quick Start

### 1. Install Dependencies

```bash
cd evals/framework
npm install
```

### 2. Start Building

Begin with Phase 1 - Session Reader:

```bash
# Create types file
touch src/types/index.ts

# Create session reader
touch src/collector/session-reader.ts

# Create message parser
touch src/collector/message-parser.ts

# Create timeline builder
touch src/collector/timeline-builder.ts
```

### 3. Run Tests

```bash
# Run tests
npm test

# Watch mode
npm run test:watch
```

### 4. Build

```bash
# Build TypeScript
npm run build

# Watch mode
npm run build:watch
```

## Architecture Overview

### Data Flow

```
OpenCode Session Storage
         ↓
    SessionReader (reads JSON files)
         ↓
    MessageParser (parses structure)
         ↓
    TimelineBuilder (builds timeline)
         ↓
    Evaluators (validate behavior)
         ↓
    TestRunner (executes tests)
         ↓
    Reporters (generate reports)
         ↓
    Results (JSON/Markdown/Console)
```

### Key Components

**Collector:**
- Reads OpenCode session data
- Parses messages and parts
- Builds chronological timeline

**Evaluators:**
- Validate agent behavior
- Check compliance with rules
- Generate scores and violations

**Runner:**
- Load test case definitions
- Execute evaluators
- Collect results

**Reporters:**
- Format results
- Generate reports
- Export data

---

## Configuration

### Framework Config

Edit `framework/src/config.ts` (to be created):

```typescript
export const config = {
  projectPath: process.cwd(),
  sessionStoragePath: '~/.local/share/opencode/',
  resultsPath: '../results/',
  passThreshold: 75,
};
```

### OpenAgent Config

Edit `opencode/openagent/config/config.yaml`:

```yaml
agent: openagent
pass_threshold: 75
scoring:
  approval_gate: 40
  context_loading: 40
  delegation: 10
  tool_usage: 10
```

---

## Testing Strategy

### Unit Tests
Test individual components in isolation:
- SessionReader
- MessageParser
- TimelineBuilder
- Each evaluator

### Integration Tests
Test components working together:
- Read real session data
- Build timeline
- Run evaluators
- Generate results

### Regression Tests
Test against recorded sessions:
- Store known-good sessions
- Run tests against them
- Detect behavior changes

## Getting Help

- Review task documentation in `tasks/eval-framework/`
- Check OpenCode logging docs in `dev/ai-tools/opencode/`
- Examine existing session data in `~/.local/share/opencode/`
- Look at validator plugin in `.opencode/plugin/agent-validator.ts`
